But this letter – written by three fans – shows he clearly has devoted followers back in Brazil as well.

‘Look at the letter I received from three beautiful fans. The letter is 1km. Thank you for caring,’ he said on his Twitter feed , handily illustrating the tweet with a photo to show he wasn’t making it up.

He has not given any clues as to what the letter says, but for his sake, we hope it’s something nice.

And the fans who wrote the letter must be glad he is still back home playing for Santos – otherwise, licking all those stamps to send it overseas by air mail would be thirsty work.
